Nike Training ClubPick a workout based on your fitness goal, level and time available. Each program includes photos and videos of the exercises as well as a timer and voice instructions to make sure you're staying on track; and you can set the entire program to your own playlist! My favorite part is the free bonus content which lets you work out alongside top athletes like soccer star Hope Solo and sprinter Allyson Felix. (Her workout targets legs and cardio drills.) It's like having your own personal trainer in your pocket.

MayMyFitnessAccuracy is key when training for a distance race and MayMyFitness makes it easy to track your workout running, walking and cycling stats. The app crunches your distance covered, pace and total time and even offers voice feedback during your workout.
